mysql5 master slave安装配置日志

背景：

master:192.168.100.231mysql5.0.19 linux

slave: 192.168.100.234 mysql5.0.18 linux

step1) 配置master

在/etc/init.d mysqld段加入

#（要同步的数据库）
binlog_do_db = test

并确保

server-id=1

log-bin=mysql-bin

step2) 授权slave

GRANT REPLICATION SLAVE ON *.* TO test@192.168.100.234 IDENTIFIED BY '123';

重启master

step3)配置slave

vi /etc/my.cnf

设置下面4行

server-id = 2

master-host = 192.168.100.231

master-user = test

master-password = 123

重启发现slave的I/O线程工作正常，而SQL线程不工作

报了很怪的错误

070307 16:30:27 [ERROR] Slave: Error 'Table 'passport.loginuser' doesn't exist' on query. Default database: 'passport'. Query: 'delete from loginuser where tokenRefreshTime<='2006-07-03 07:00:00'', Error_code: 1146
070307 16:30:27 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'mysql-bin.000001' position 98

因该是relay log中的数据有问题，于是在

将master机器上的数据拷到244，发现还是有问题。

于是在/etc/my.cnf中加入

replicate-do-db=test

重启slave,

show slave status发现两个线程工作正常

5)测试

在master的test数据的user表中添加了一条记录

然后在slave上通过show processlist看slave工作情况一切正常，

再查数据库数据似乎没有更新，查看slave错误日志

070307 16:45:16 [ERROR] Slave: Error 'Can't create database 'test'; database exists' on query. Default database: 'test'. Query: 'create database test', Error_code: 1007
070307 16:45:16 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'mysql-bin.000040' position 70671

原来都是我当初拷贝数据惹的祸，因为主机日志在我建数据库的时候就开始了，所以我拷贝数据多此一举，于是

我删除拷贝的表，一切ok
